摘要： 三容水箱液位控制实验系统具有非常强的耦合性、同时其变量多样化,极为复杂。然而该系统因为在很多现代化设备中都有所应用,具有很强的实验价值.因此本文对该实验系统进行了全方位的介绍.30004
首先本文对三容水箱液位控制实验系统的物理硬件配置金形子了全方位的概述，之后又根据其具有变量进行了进一步设计，同时建立了以被控液位为基础的数据模型，再将这些模型进行了性能的探讨。可见,本研究内容主要与教学改革的背景息息相关。本实验平台能够对实际工业运用中有关液位、流量等测量的有效地模拟，同时能够此类给以控制、测量和观测。其因为逼真的效果，具备了极强的实验能力；具有很好的人机界面功能。并可以更为直观地反映水箱液位。

Abstract：Three tank water level control experimental system is a nonlinear, strong coupling, multivariable and complex systems with large delay. This paper introduces three tank water level control system means physical experimental system, then designed several typical multi-variable level control experiments, and gives the Mathematical model, and finally the system described above controlled object controllability and observability analysis. The reform project was subject to laboratory background. The experimental platform is the "three - tank" as and Key Laboratory of Experimental device control object "industrial process control and simulation laboratory" Symphony provides distributed control systems together to form a closed-loop control system. It can simulate the industrial production process level, flow and other variables, and these variables are controlled, measured and observed. The comprehensive experimental platform has a powerful experimental features, to complete the first order and multi-stage object. Multiple input - multiple output decoupling experiments; has good man-machine interface functions. Visual display of the tank level.
